netns-ctl - Bash script to create a network namespace on linux

We know linux supports namespaces. A network namespace appears to have a standalone TCP/IP stack. This project provides a bash script netns-ctl to simplify the work of creating and deleting a network namespace.

This project is inspired by this page.

Creating a network namespace

Simply run netns-ctl as root, it creates a new network namespace. Features:

• There is a "lo" interface in this namespace.
• There is a virtual ethernet interface in this namespace.
• Programs in this namespace can access internet as if it's another computer.

For more options, check output of netns-ctl -h.

Deleting the network namespace

Run netns-ctl -c.

Launching a shell in the network namespace

Run netns-ctl -s.
